T 0 all whom it may concern 4,

Be it known thatwe, FRANK M. Ronnms and Josnrn S. HARTL Y, citizens ofthe United States, residing at Chattanooga, in the county of Hamiltonand State of Tennessee, have invented certain new and usefulImprovements in Conveyor Cleats, of which the following is aspecification.

This invention relates to cleats for use with conveyors for handlingslabs, sawdust. shavings or other material.

An object of the invention is to provide a cleat of simple and ruggedconstruction which maybe easily and securely attached to a conveyorchain. A. further object is to provide a cleat which may be attached toand detached from a chain without the use of special toolsor of bolts orrivets. A further object is to provide a cleat which may be firmlyattached to chains having links of different size or to. a chain havinglinks which have become worn in service. More specifically an object ofthe invention is to provide a cleat which is attached to a chain by--means of a removable wedge which is locked in position by means ofmalleable projections.

Some embodiments of our invention are disclosed in the accompanyingdrawings, in

which Fig. 1 isan end elevation of a cleat 011 a conveyor chain; r

Fig. 2 is a front elevation of the same; Fig. 3 is a plan view;

Fig. l is a horizontal section of the butt end of the cleat, and takenon line i-t of Fig. 2;

Fig. 5 is a fragmentary end elevation illustrating modifications in theconstruction disclosed in Figs. 1-4; inclusive;

Figs. 6 and 7, are respectively a fragmentary end elevation and a plan.of another embodiment of the invention;

Figs. 8 and 9 are, respectively a. fragn1entary end elevation anda planof another embodiment v Figs. 10 and Ham respectively, a front elevationand a plan of another'embodiment;

7 Figs. 12 and 13 are respectively, a front elevation and a plan of afurther embodiment, and

In the drawings, thelinks of the conveyer chain to which the variousforms of cleats are attached are designated by the character L. In theembodiment illustrated in Figs. 1 to 4 inclusive, the butt end of themain section of the cleat 1 is provided on its lower face with a groove2 for receiving one side of a link L. The upper face of the main section1 has formed therein a cylindricalsurface subtending an arc ofapproximately 90 which provides a link receiving seat 3 for thereception of the opposite side of the link L. Adjacent the seat 3 themain section is provided with an approximately vertical wall 4:, asecond wall 5 being spaced therefrom and located near the end of thecleat. .The walls 4 and 5 define a recess or slot across the end of thecleat, the bottom surface of the recess being formed by the surface 6which connects the walls 4 and 5. A clamping member 7 in the recess hasa seat 8 which cooperates with the seat 3 of 'the mainsection to form alink groove. The member 7 is locked in position by means of malleablelugs 9 formed thereon which may be bent over to lie in recesses 10"formed in the adjacent portion of the main section 1.

In the embodiment of our invention illustrated in Figs. 1% inclusive,the walls 4, 5 are undercut to form a dovetail recess and the wall 5 isinclined to the axis of the link recesses, thus providing a taperedrecess or slot. The member 7 has a corresponding dovetail wedge shapeconforming to the shape of the recess. faces of the removable member andthe cleat may be smooth as shown in Fig. 2, or if desired these surfacesmay be corrugated as shown in Fig. 5. Fig. 5 also illustrates a furthermodification in that the member 7 does not encircle substantially onehalf of the link L but terminates substantially at the upper surface ofthe main section of the cleat 1.

Ihe cleat shown in Figs. '6 and 7 is similar in construction to thatabove described, but the positions of the malleable lugs and recesseshave been reversed. In this form the lugs 9 are located on the end ofthe main section 1' and the cooperating recesses are formed in theadjacent surface of the member 7 As herein shown the cleat I has beenapplied to a link which has a span between the opposite sides of thelink which The contacting suris greater than the distance between therecess 2 and the seat 3. Due to the taper of the walls 4-, 5, the wedgemember 7 holds the cleat firmly to the link L even though the link isnot perfectly seated on the cleat. As will be obvious this constructionalso permits the cleat to be firmly attached to links having sideportions of a radius slightly greater than that of the link receivingseats.

In the form illustrated in Figs. 8 and 9, the walls 4:, 5 are nottapered, but the lower face of the recess has formed thereon a tapereddovetail 6? which isengag'ed by a correspondingly shaped recess in thelower face of the member 7 As with the forms previously described thiscleat may be firmly attached to links of somewhat different size in viewof the'taper of the cooperating parts on the member and the main sectionof the cleat. Y

Figs. 10 and 11 illustrate a universal cleat 12, that is one whichextends to both sides of the conveyer chain. A chain receiving recess 13and a link seat 14 are formed respectively in the lower and uppersurfaces of the cleat. Adjacent the seat 145, the main section of thecleat is provided with a transverse recess of tapered dovetailconstruction for the reception of a locking wedge 15 upon which areformed malleable lugs 16 which may be engaged in recesses 17 formed inthe cleat. Obviously the height and thickness of the main section of thecleat are so proportioned that the cleat may be slipped into a chainlink andothen rotated through 90 position for attachment. It isalsooobvious that in place of using a form of wedge mcmber 12 similar tothat illustrated in Figs. 1-4L inclusive, attaching means constructed asshown 'in Figs. 5-9 inclusivemight be used. 1

A further form of universal cleat embodying our invention is illustratedin Figs.

'1214 inclusive, in which the main section of cleat is designated by thenumeral 18.

' On its rear facethe main section 18 is provided with an extension 19which terminates in a vertical surface passing substantially through thecenter'line of the cleat. The

upper and lower portions of the extension 19 are provided with linkreceiving seats 20 and 21, respectively. Upon the opposite side of thecenter line of the cleat, the main section -18 is provided on its rearface with a tapered dovetail projection 22 having a notch 28 formedtherein near its outer end.

The cleat is held to a chain link L by means of a member 2a which hasformed in its lower surface a tapered dovetail recess by means of whichit may be slid into position along the back of the main section 18. Themember 24; is provided with upper and lower link seats 25 and 26 whichcooperate respectivelywith the seats 20 and 21 to form link 'rece'sws.The outer end of the memberQ thereby as many changes may be made in thevarious parts, their relative location, size andproportion.
